There are no numbers to fudge because there is no single verified figure. It all depends on who you trust - the Pakistani state narrative that has zero credibility or the Bangladeshi state narrative or an independent research by the BBC that has revealed curiously little information of its research methods and proofs. Same goes for the number of women our soldiers raped.
Maybe Pakistan is telling the truth for once, maybe Bangladesh is lying, maybe the BBC research is very accurate. We don’t know. However, what we do know that the Pakistani state did commit a genocide and Pakistanis soldiers did rape Bengali women. Furthermore, the above quote by General Yahya is also a fact.
Hence, it is not about the numbers it is about the principal. It doesn’t matter how many we killed and how many we raped. What does matter is that we did kill innocent people, raped women and our president stated that if we kill three million Bengalis, the rest will surrender.
I believe consistency is the key to the credibility. You cannot have selective narrative to suit your needs and discard that doesn't suit you. That is not how it works. Nor the credibility is formed based on assumption. Credibility is based on concrete evidence or better yet, the historical pattern that may form strong opinion but not enough to form credibility.
As you just said that maybe Pakistan is telling the truth is similar assumption as Bangladesh is lying or Bangladesh is telling truth and Pakistan is lying. Either way, there is no way to conform to the conceived perception that Pakistan committed genocide or rape for that matter. So maybe it is best to discard ill conceived perception about Pakistan that is not true, or better yet, lack of concrete evidence to suggest prior to the case or otherwise.
Back to the principal, as i said earlier that consistency is the key to the credibility. Therefore, the principal in this case is out of question since the credibility of the narrative from Bangladesh and India altogether is already questionable as it is.
Whereas for historical pattern, only India has the history of resorting to genocide and committing rape culture in massive scale for decades which to the point earned the title 'rape capital' in the eyes of the worlds. Whereas Pakistan military doesn't have that kind of reputation nor being genocidal for that matter.
Take a look at Modi at Gujarat incident 2002, Indian army in Indian Occupied Kashmir since independence of Pakistan/India, and the female infanticide on the massive level along with the rape capital culture of India as whole including NRI Indians that migrates the rest of the worlds where you hear the news about Indians involvement in rape all the times.
Therefore, it is my strong opinion as why i believe Indian armies used Pakistani dress to commit genocide and raped women since only Indian armies and Indians as civilians are capable of practicing genocide and rape given the misuse of beef laws and mistreatment towards women in general.
Whereas for Pakistan in Balochistan, that is to suppress the voice that uses foreign funding to seek separation in form of revolting; however, it is arguable to suit either way. As for record of Pakistan army's performance in Azad Kashmir, it is well known given the exemplary contribution from Pakistan army as to why not just Azad Kashmir that still continue to stay loyal while Kashmiris in Indian Occupied Kashmir always aspire to be with Pakistan. The credibility of public and its support cannot be that blind as compared to Indians and Indian NRI regarding Modi, Indian Occupied Kashmir and rape capital.
